3x^2-6=-14 in imaginary solution simplest form

GREYUIT [131]

Answer:

$x=\pm2i\sqrt{\frac{2}{3}}$

Step-by-step explanation:

we have

$3x^{2}-6=-14$

Solve for x

Adds 6 both sides

$3x^{2}-6+6=-14+6$

$3x^{2}=-8$

Divide by 3 both sides

$x^{2} =-\frac{8}{3}$

square root both sides

$x=\pm\sqrt{-\frac{8}{3}}$

Remember that

$i=\sqrt{-1}$

so

$x=\pm i\sqrt{\frac{8}{3}}$

simplify

$x=\pm2i\sqrt{\frac{2}{3}}$

A car traveld 32 miles in 4 hours at this rate how many miles will the car travel in 0.5 hours

Mandarinka [93]

Answer:

4 miles

Step-by-step explanation:

In order to find how many miles the car will travel in 0.5 hours, we can set up a proportion.

$\frac{32}{4} = \frac{x}{0.5}$

We can now cross multiply to find the value of x.

$32 \cdot 0.5 = 16\\\\16\div4 = 4$

So the car can travel 4 miles in 0.5 hours.

Hope this helped!
